1) Probably have zero mobility in my legs.
2) Go down the long laundry list of people close to you who have died
3) My penis is useless at that point, so why live?!
4) Technology will be pretty advanced. Screw trying to learn all that.
5) Penis...completely useless. Only use I'll have for it is to use it as a flap to keep the dust out of my butt crack.

Assuming my body isn't absolutely ruined and useless(it would be...) for sure wake up. It would be indescribably awe inspiring to see what the technology has advanced to, catch up on the history of what's been going on, who the best fighters that came along are, etc...would be fun as hell

At 38 I would rather die, my family would get my life insurance and that would see my kids to a good start. I'd rather they didn't have me hanging on as a ghost they had to feel guilty for. I'd prefer my wife to move on also.
